Abstract
The anhysteretic contact printing process was simulated by a computer with the Preisach diagram which was modified by the Onsager field effect. The printed magnetization was determined by successive magnetizations at each peak of the decreasing transfer field. The second quadrant demagnetization was also discussed afterward, but the effect of the reproducing head was not included. The actual magnetization will be situated between the magnetization before and after the second quadrant demagnetization. As a result of the simulation, considerable saturation was found at the surface layer of the printed tape when the input signal intensity of the recorded master tape becomes large. The transfer efficiency decreases rapidly, corresponding to the increase of the signal field intensity. These results show qualitatively good agreement with experimental results published heretofore.
